TETRAMIX type static mixers
|Standard TETRAMIX mixers
The TETRAMIX static mixer was designed for mixing identical or different substances, particularly liquids with liquids, liquids with suspensions, solid granular or powdery substances or materials or for mixing gases, with gas or gas mixtures.
|It’s built-in special elements divide and combine the material to four parts, then again and again they divide the stream into four, mixing it, so that each element quadruplets the number of previous divisions after, e.g. 12 elements mathematically generate more than 16.7 million divisions and their variations.
The divisions are optimised by the 4 spindle-like vortex currents that form immediately downstream of the mixing element, resulting in "tunnel-free", space-filling perfect mixing.
|Therefore, two different mixing mechanisms operate simultaneously, where the dominant mixing form is determined by the material properties of the substances to be mixed - e.g. density, viscosity, temperature...etc.
A unique feature of the TETRAMIX static mixer is the ability to combine the formed partial vortex currents with direct fluid flow collision.
The TETRAMIX static mixer perfectly meets the general requirements for this type of equipment. Its versatility is also supported by other useful features such as:
- have a large free flow cross-section,
- mixing elements have a robust, rigid, impact-resistant design,
- the shape, form and size of the mixing element allows for flexible variation,

TETRAMIXC and TETRAMIXCi mixers
The TETRAMIXC type static mixer is virtually identical to the standard TETRAMIX static mixer in all flow pattern characteristics, but offers additional benefits through the increased swirl chambers of the mixing elements.
One of the most useful functions is to smooth the intermittent flow of chemical nozzles, which are fed in stages in front of the mixer, making it continuous, with perfect mixing.
The TETRAMIXC mixing element is a modified version of the TETRAMIXCi mixing element, which, thanks to its curved geometry, further enhances the variability of the mixer design, essential for optimising the mixing task.
This variability allows the pressure loss during mixing to be adapted to the specific requirement.

The picture above is a good representation of the excellent operation of the special internal vortex chamber, which is able to mix the gas bubbles entering and floating up at one point immediately after the shredding and in the full cross-section.
The following snapshot is an example of liquid mixing:
For the flow image illustrating the mixing format, the parameters v~0.33 m/s; Re~20 500 and CoV<0.04 are used.
The same mixing formation is achieved in gas-gas mixing, but with significantly more intense speed components and high Reynolds number and mixing efficiency.
Polymix design static mixers
Polymix static mixers are designed especially for mixing low and medium viscosity liquids with liquids and low viscosity liquids with gases.
This solution adds a number of innovative and useful features to the equipment, both during production and operational use ( e.g. the removability and cleanability of the mixing unit).
Built with the standard TETRAMIX mixing element format, the TETRAMIXPT static mixer, a polymix design, has all the advantages of the TETRAMIX mixer, but with extra short mixing path lengths due to the t=0 mm spacing. The TETRAMIXPT static mixer built with elements rotated at 30 or 45 degrees to each other, it is recommended for mixing medium to high viscosity liquids.
|TETRAMIXPC and TETRAMIXPCI
TETRAMIXPC and TETRAMIXPCI static mixers are also provide extra short mixing path lengths but these mixers stand out from the rest by increasing the likelihood that the intermittently dosed chemical will become continuous after perfect mixing. This is achieved with the help of enlarged vortex chambers in the mixing elements.
The TETRAMIXPC and TETRAMIXPCI static mixers are ideal for mixing low viscosity liquids and gases in liquids.
The TETRAMIXPK static mixer optimises mixing and therefore the most diverse production technology by means of a mixing element assembly, which is specially designed and linked in a chain of sub-elements. In the mixer, rotation, partial flow and vortex formation are simultaneously present, combined with significant shear forces. Because of the high shear force generation, TETRAMIXPK Static mixers can be used with good efficiency for mixing low and medium viscosity liquids and liquids with gases.
Droplet separationStatic mixers of the TETRAMIXPK type are well suited for the separation of trapped liquid droplets from various gases. Since the liquid droplets transported by the gaseous medium cannot follow the rapid change of direction, the rotational motion, sooner or later they will separate as a result of collisions with the mixing elements.
ETRAMIXPRThe TETRAMIXPR is a special version of the TETRAMIXPK static mixer, which is typically designed for mixing and homogenizing medium to high viscosity liquids. A very useful feature of slotted mixing element plates is that the fluid flowing through them, in addition to the multiple splitting, is forced to undergo a kind of rotation, elemental volume exchange.
With this combination of motions a very effective mixing can be achieved when performing the type of tasks where the flow pattern of the mixture in the pipeline has the characteristics of purely laminar flows.

Turbomix type static mixers
The Turbomix family of mixers is designed for mixing identical or different fluids, in particular gases with liquids and liquids with liquids.
In this mixer formation, the main emphasis is on the large number of splits created by the paddles and the formation of beads.
The special placement of the mixing element blades results in the flowing liquid or liquid and gas mixture, after a collision, splitting and separation creating a significant shear force, undergoing intense mixing in the vortex chamber section and then exits the chamber in a whirling motion. The sequential triple motion combination ensures highly efficient mixing even with a single mixing element.
A further way to increase the efficiency of mixing is to use several mixing element units in succession to create a right- and left-side whirling motion.
Dense paddling, multiple collisions, directional changes caused by multiple mixing elements and relatively high shear force generation, especially when mixing gases in liquids, are of great help but also effective in gas-gas and high viscosity liquid mixing.

For mixers of this type, special mixing channels are created with so-called full scooping. In channel cross-sections that vary continuously in the axial direction, primary mixing (partial flow mixing) is already achieved downstream entry and exit, the channels defined by the blade number are merged, where good mixing is optimized by the outward swirling of the blade edge.
We can also use mixing units with right- and left-swirling vortex motion, which can be installed in different combinations in a single mixer
TurbomixTL mixers can be used for low to medium viscosity liquid-liquid mixing.
We have added to our product range a 2 in 1, i.e. two-in-one, static mixer with a transparent PVC pipe housing, which can perform two tasks simultaneously during installation and application, namely
- mixing i.e. technological and
- flow monitoring i.e. operational taks.
- The 2-in-1 mixers are typically static mixers of Polymix design, which are beneficial for use in both plant and semi-plant environments or as laboratory mixers for various measurements and experiments.
